Specification of Redispersible Polymer Powder RDP Concrete Admixture for Exterior Wall Insulation and Finish Systems

Återdispergerbart polymerpulver (RDP) for Outside Wall Surface Insulation and Complete Solutions

Vad det är

Återdispergerbart polymerpulver (RDP) är ett fritt flödande, white powder utilized in dry-mix mortars. När det blandas med vatten, it creates a flexible polymer movie that binds products together. This item is specifically made for outside wall insulation and finish systems (ETICS or( EIFS).

Trickförmåner

RDP substantially improves adhesion. It aids the skim coat stick firmly to insulation boards like EPS or mineral wool. The powder additionally improves flexibility. This implies the layer can handle small motions without splitting. Vattenmotståndet ökar också, so wall surfaces stay secured from rainfall and wetness.

Arbetsbarheten förbättras också. The mix ends up being much easier to spread and trowel. This saves time and effort throughout application. RDP also enhances communication inside the mortar. That minimizes sagging on upright surfaces and maintains the layer also.

Tekniska funktioner

– Titt : Frittflytande vitt pulver
– Lägsta temperatur för filmbildning : Typiskt 0 °C till 10 °C (differs by grade).
– Askmaterial : Runt 10– 15%.
– Bulkdensitet : Ungefär 0,4– 0.6 g/cm FEM.
– Återdispergerbarhet : Totally redisperses in water to develop a steady emulsion.

Hur man använder

Include RDP straight into completely dry active ingredients like concrete, sand, och ingredienser. Mix extensively before including water. Regelbundna dosmatriser från 1.5% till 4% of total completely dry weight, depending on performance needs. Always comply with the supplier’s guidelines for best results.

Förvaringsutrymme och hantering

Maintain the powder in a cool, torr plats. Shop bags off the floor and away from dampness. Usage within one year of production date. Seal opened up bags firmly to stay clear of clumping.

Applications of Redispersible Polymer Powder RDP Concrete Admixture for Exterior Wall Insulation and Finish Systems

Applications of Redispersible Polymer Powder in Exterior Wall Systems

Mer kraftfull, Smarter Wall Ends Up

Återdispergerbart polymerpulver (RDP) is an essential active ingredient in modern exterior wall surface insulation and coating systems. When blended into cement-based mortars, it significantly improves efficiency. The powder dissolves in water throughout blending. It then develops a flexible polymer movie as the mortar dries. This film binds materials together a lot more snugly.

Mycket bättre vidhäftning
RDP helps the finish stick firmly to insulation boards like EPS or mineral wool. Utan det, layers might peel off or crack over time. Med RDP, the bond remains solid also under temperature level swings or hefty rain.

Water Resistance Without Trapping Moisture
The polymer movie obstructs liquid water from going into the wall surface. Samtidigt, it enables water vapor to escape. This equilibrium maintains walls completely dry inside while protecting against mold and mildew and rot.

Adaptability That Lasts
Outside walls increase and contract with weather modifications. Average cement can fracture under this anxiety. RDP includes flexibility so the covering moves with the wall. Splits are much less most likely to create.

Resilient Surface Defense
Completed with RDP stand up to wear from wind, UV-strålar, och föroreningar. They keep their color and structure longer. Cleansing is less complicated as well, considering that dust does not stick as much.

Contractors and specialists pick RDP-modified mortars because they conserve time and lower repair work. The product works well in thin-layer applications, which accelerates installation. It also fulfills rigorous building codes for energy performance and weather resistance. Whether utilized in brand-new construction or improvement, RDP gives trustworthy outcomes that last for many years.

5 FAQs of Redispersible Polymer Powder RDP Concrete Admixture for Exterior Wall Insulation and Finish Systems

Vanliga frågor om återdispergerbart polymerpulver (RDP) for Exterior Wall Systems

What is RDP and why is it used in exterior wall insulation?

Återdispergerbart polymerpulver (RDP) is a fine powder made from special polymers. När det blandas med vatten, it forms a flexible film inside cement-based materials. This film makes the mortar stronger, more waterproof, och bättre på att hålla sig till ytor. It is essential in exterior insulation and finish systems (EIFS) because it helps the coating resist weather, sprickor, och fukt.

Hur förbättrar RDP vidhäftningen?

RDP creates a sticky polymer network in the mortar. This network bonds tightly to insulation boards like EPS or mineral wool. Utan RDP, the base coat might peel off over time. Med RDP, the bond stays strong even under temperature changes or rain.

Does RDP help with crack resistance?

Ja. The polymer film from RDP adds flexibility to rigid cement. This means the coating can stretch slightly without breaking. Small movements in the wall—caused by heat, vind, or settling—won’t easily cause cracks when RDP is used.

Is RDP safe for outdoor use?

RDP is designed for long-term outdoor exposure. Den står emot UV-ljus, regn, och frys-upptiningscykler. En gång botad, det släpper inte ut skadliga ämnen. It meets international standards for building materials used on exterior walls.

How much RDP should be added to the mix?

The right amount depends on the product and application. Vanligtvis, 2% till 6% of RDP by weight of total dry ingredients gives good results. Följ alltid tillverkarens instruktioner. Too little may weaken performance. Too much can make the mix too soft or slow to set.
